Avalanche Summary

A widespread natural and human-triggered avalanche cycle has occurred since Friday. Expect avalanche activity to continue through the forecast period.

Snowpack Summary

Up to 60 cm of new snow has fallen on a variety of old surfaces. There is surface hoar, more prevalent around treeline and below, a crust on sun-facing slopes, and 20 to 30 cm of low-density faceted snow in sheltered areas.

Dry January conditions have created a weak, faceted upper snowpack with multiple surface hoar and crust layers. The new snow will likely not bond well with these layers.

The lower snowpack remains generally well-settled and strong.

Terrain and Travel Advice

  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Conservative terrain selection is critical; choose gentle, low consequence lines.
  • Give the new snow several days to settle and stabilize before pushing into bigger terrain.
